some of the newer washing machines liquids seem to contain no foaming agents ( usually SLES ) which i'd say added for visual effect more than anything .
heres a suitable one ...' Formil bio/nonbio ' from Lidl
Its cheap and concentrate ... contains everything you'd find on some of the pro cc products ... was thinking of making up 20 liters for nuckin thrashed rentals etc ... which often dont deserve your £££ products ? ...
Doesn't foam but you could add more defoam or some perfume Deodorizer to make it your own ...
